For generating ROI chromatic indices the python library vegindex (0.7.2) in python is used. For calculating hazeness values the R hazer (1.1.1.) and jpeg (0.1) libraries are used. Data Creation SuperSites Vegetation Monitoring Protocol - 17.1.7 AusCover WingScapes RGB Digital Camera Set Up Credit The research site was established in 1995 by Forestry Tasmania and joined the TERN SuperSite Network in 2013. This work was jointly funded by the Terrestrial Ecosystem Research Network (TERN), an Australian Government National Collaborative Research Infrastructure Strategy (NCRIS) project. Purpose Time series of vegetation phenological observations are collected to understand ecosystems annual cycles. Phenological timeseries can be used for ground-truthing remote sensing data products, for studies of climate change impacts on terrestrial ecosystems, and as a standard for earth system models. Fixed cameras installed at the Warra Tall Eucalypt SuperSite provide a time series of fine scale data as a long-term record of vegetation structure and condition. This dense time series of phenocam images provides data for analysis of ecological responses to climate variability, and when consolidated across the entire terrestrial ecosystem research network, supports calibration and validation of satellite-derived remote sensing data, ensuring delivery of higher quality results for broader scale environmental monitoring products. Images are captured hourly during daylight hours. Images and data products, including timeseries of the Green Chromatic Coordinate (Gcc) for a region-of-interest (ROI) that delineates an area of specific vegetation type, are made available on a regular basis. The Warra Tall Eucalypt SuperSite was established in 2012 and is located in a stand of tall, mixed-aged Eucalyptus obliqua forest (1.5, 125 and >250 years-old) with a rainforest / wet sclerophyll understorey and a dense man-fern ( Dicksonia antarctica ) ground-layer. The site experienced a fire in January 2019, which consumed the ground layer ...
